Monsters, Magic and Power Armor

Sword and sorcery? It's nothing more than magic-driven chainswords, magic guns, and knightly power armor. Apocalyptic crisis? But they are not zombies, but various steel monsters that have evolved over thousands of years after artificial intelligence and nanomachines awakened their self-awareness. Humans and elves? However, it is a cruel society where all members are mixed-race, each possesses a set of magic organs, and are divided into three, six, and nine grades based on their magic talents. The mobile fortress - Lonely City, the last spark of civilization, is wandering in the never-ending magic storm, holding on to the last bit of vitality of civilization. Arthur, an untouchable boy who was born in the lower-level ghetto of the fortress. His mother is suffering from petrification, his sister needs high tuition fees, and without the talent for magic, he can only make a living by mining and carry the burden. But what everyone doesn't know is that Arthur is not simply lacking in magic talent. He is actually a pure-blood human who has no magic organs in his body due to his high degree of atavism! The legendary story of Arthur begins with him pulling out an ancient giant sword deep in a mine that only pure-blooded humans can wield...
